Province of Que c, Dominion of Canadfu have inventedroitnin new und useful linprovements in Spi-ing Structures for Rail- Wuy-Car Trucks; and I do heiehiv dechire that the following is n full` clear. :1nd exact description of the suine,

My invention teintes moto p-.articnlui'ly to the construction ot' the jonriml-boxes und the portions of the truck from@ inunedintvly contiguous thereto. and il hns for its: obje@ to ffiinpify eguali mechanism The invention may lie said briefly to cow sist iu tlm construction of the journal-hows with un cxirndcd Spiingpseat to imoounnw date ull thc spring, usuully sented upon the equalizer bars, the upper ends ot the springs according to my invention hearing within the side-sills which :irc made, hollow for they purpose of noting upon the underside of ther top thereof. The usual eqiutlimci oms uw dispensed with.

For full conii'n'ehf ision. however. of my invention reference must he had to the nc- -ompunying drawings 'forming a part of thinv speciiivntion in which Similar reference characters indicate the sume parts, and wherein Figure 1 is a side elevation partly in section of a truck constructed according to my invention; Fig. 2 is a vertical sectional View thereof taken ofi line A A Fi 1 and looking in the. direction indicatief: Fig. 3 is a vertical sectional view taken on line Il B Fig, 2 :1nd looking in the direction indiA cnled und Fig. 4 is n detail perspectiva View of the niournnbboxes removed.

The truck in the main may be of ugual vonslruction with sideiills euch consisting ot' :1 puin' of'ulmunoiirons b arranged with theiilunt'fes toward cach other, suoli oido sills lin ving: their component pruts united tov gethcr and thc sills themselves boing united h v transoms 2. gussebplntcs 3, and other parts common to the construction of railway trucks. und forming no pax-t of mi invention.
